[Zope-dev] Re: Comments on ZPatterns
At 03:10 PM 6/28/00 +0100, Chris Withers wrote: 1. Too much jargon... by far... Lots of complicated words that are meanlingless to the layman and don't help to convey the concepts. Yep, like "Acquisition" and "object publishing". :) Seriously, that is very much the level we're talking about here. ZPatterns is an evolution to Zope's revolution, in the area of web-based application development models. Zope says the answer is publishing objects in an environment supporting acquisition. The ZPatterns design approach is an attempt to answer to the question, "So what objects should I publish, and what are the appropriate uses of acquisition?" As with Zope itself, it is both a design approach *and* an implementation toolkit for the approach, which certainly doesn't help the confusion. :) Also, as in the early days of Zope, terminology evolves and changes as the developers of the concepts seek better ways to explain them to other people. As an example, "Specialist" was originally called "Interface" by Ty and I back around September or so. It evolved to "Implementation Provider" in the later part of the year, and "Implementor" by the time of our conference presentation. After using that name on the lists a while, and in developing the ZPatterns code, it became clear that the name still really sucked and we needed one that made more sense on initially encountering it. After considerable brainstorming, the term "Specialist" was born, and on the whole we're happy with it. Other terms are still in flux, and many I hope we can do away with by replacing them with simpler, more powerful ideas (such as replacing all of the different Trigger and Provider plugins with a simple declarative scripting syntax that lets you specify the aspect weaving for your objects). 2. Feature runaway. It seems every day something new (and more confusing) has been added to ZPatterns. I think ZPatterns will only work if it is kept as simple and functional as possible. My view (bearing in mind my limited understanding ;-) would be to concentrate on Containers, Container Groups and Plugins on the one front and Racks, Specialists and the various providers and agents on the other. Been there, done that, actually. There really hasn't been much change in ZPatterns from 0.3 to 0.4 in that regard. Most of the upheaval has been due to making it possible for the capabilities of "Rackmountables" to be used in non-rack settings. This forced some significant generalization of the model and some extension to the "theory" in the area of the internal event model (which was previously incomplete and too hardwired). Believe it or not, in 0.4 I have actually *removed* some previously existing data management plug-ins. The acquired attribute provider and acquired sheet provider classes were replaced with a generic "link to parent data plug-ins" class, for example. As Ty mentioned in his post on this subject, we will be trying to do away with other such features later, replacing them with general-purpose tools. Unfortunately, all this evolution makes ZPatterns a moving target for comprehension at the moment. In spite of this, my reading of the lists seems to indicate that there are a few people besides Ty and myself who are actually achieving results with the framework. I hope that they can help to provide more accessible how-to materials, because I'm still very focused on *finishing* ZPatterns to the level that my "paying job" requires. And it's likely going to be a few months before my "paying job" requires that I have introductory docs available for the tools (although I'd personally really like to have some available before then). ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Seriously, I'm trying to get it all figured out, and I thought maybe
if I attempted to do something 'real' with it I would at least learn
what I *don't* understand. Well.. I've learned a *lot*! (about what I
don't understand.. ) ;-) The source code is astonishingly simple
looking, but about one layer deeper that I can easily grok, apparently.
That's an unfortunate side-effect of applying Demeter's law... it's easy
to grasp (in an abstract way) local implementation aspects, but hard to
grasp how the actual *concrete* implementation works from looking at the
pieces. It's the "there's no *there* there" effect, as Ty dubbed it.
I also create a "TableInfo" ZClass, subclass of DataSkin, that
quantifies the kind of data the customers have to choose from, and
metadata about the data (headers, query parameters and suchlike).
I create a ZClass property sheet for the TableInfo ZClass.
Finally I create an instance of Specialist (tableManager) with a
(default) rack of TableInfo objects.
Now... some of the Tableinfo properties, and some of the View
properties are *really* in MySQL. I figured out, from the mail list
and the source code, that I can create a Generic attribute provider in
the rack that can get attributes from an SQL database for my DataSkin
descendents using the 'source expression' and 'target expression'
business.
Congratulations, you found the top secret documentation. :)
Source expression:
(GetTableInfo(tableInfoID=self.id) or [NOT_FOUND])[0]
Target expressions:
tableHeaders=RESULT.tableHeaders
footnote=RESULT.footnote
and when I ask one of my TableInfo instances for their footnote it
comes right out of MySQL! Cool. Now.. I can't seem to figure out how
to *change* the data in the database when the user 'edits' the
DataSkin which brings up the whole issue of changing stuff in
DataSkins.
Here's some more top-secret documentation... Use a GenericTrigger to
implement attribute changes. Set up your trigger to be activated on object
changes, and set the trigger expression to call an SQL method, e.g.:
UpdateTableInfo(object=self,CHANGED=CHANGED)
In the SQL method, code something like this:
UPDATE mytable
SET
dtml-if "CHANGED('attr1')"
attr1=dtml-var "object.attr1",
/dtml-if
...
WHERE primary_key='dtml-var "object.id" sql_quote'
with an "if" block for each attribute you might want to update.
Last part, and this is the trick that's not yet documented... set the "Set
Attrs" field to be a list of the attributes you want the trigger to handle
set/delete operations for. (You don't need to put anything in the
"Keeping" field unless you need a "before" value of an expression to use in
your SQL.)

Re: [Zope-dev] ZPatterns: DropZone example
At 05:26 PM 6/28/00 +0100, Steve Alexander wrote: The suggested specialists in the Accounting framework are: Invoices Orders Customers Products What I'm finding is that these are just the White-box specialists. A clean design would seem to want all the specialists above, plus at least one Black-box specialist to do the "heavy lifting. Let's call it the "AccountingProcessor" specialist. Keep in mind that a Specialist doesn't just "store" a bunch of objects, it also provides *methods for dealing with sets of objects*. So an Invoices specialist could usefully contain a wide variety of reporting methods, for example. Similarly, the Customers specialist might have a method to post balances forward on all customer accounts whose statement cycle is in a certain date range. These are all "heavy lifting" from an accounting point of view, but perfectly valid to have in the white-box specialists. White-box doesn't mean that there's no implementation; it just means that the implementation is intended to be extensible or integratable by someone other than the framework's original developer. Now, if I had a third-party accounts package (something by Sage perhaps), I could make the AccountingProcessor specialist expose various functions to the four other White-box specialists. It would implement these by making equivalent calls on the underlying accounting package. I could also swap the heavy-lifting portion of my framework by swapping the black-box AccountingProcessor specialist for one that talks to some software by Quicken, or perhaps some software that is written in Python as a conventional Zope product. That's all quite true, but it would probably be simplest to do such a thing using AttributeProviders and SheetProviders in the white-box specialists. It does seem reasonable to have those providers talk to an AccountingProcessor object if you want to make your framework talk to different back-ends, but I think it is misleading and incorrect to call AccountingProcessor a specialist, as it's not an application-level service object, but a private implementation helper. Interestingly, you've just given me what may be a motivating example for using Shane Hathaway's DatabaseAPI in conjunction with ZPatterns, assuming of course that I've correctly understood his most recent explanation of the DatabaseAPI product. The same goes for the Resource Scheduling framework. We have some White-box specialists, ripe for customisation: Resources Reservations ResourceUsers And then for the heavy-lifting we have the black-box ResourceScheduler specialist. Again, this might be a Zope Python Product, or it might be an interface to some application written on top of Microsoft Exchange. Again, look to what these specialist would do besides look up objects. For example, utilization or load-balancing reports. Generating bills for usage. Generating calendars for individual resources. Checking for conflicts. Etc. Are specialists intended to be placed inside other specialists, as "contents"? You *can* do this, but I've not yet encountered a real-life situation where I *would* do this. (Mike has given some examples that suggest it might be useful under some circumstances, however.) So in this case, would the white-box specialists live inside the black-box specialist -- so they become the customisable aspects of the overall framework? Or would both black-box and white-box specialists live inside an uber-specialist? If anything, the black box should be inside the white. Otherwise, you are creating confusion between heaven and earth. :) Seriously, the white boxes are the parts you will reference in URL's most often, so why have /AccountingProcessor/Invoices/ when you can just have /Invoices/? If you have to share a black box among white boxes, acquire it. If your "root" gets too messy, then make an "Accounting" folder and put Invoices, AccountingProcessor, and the rest inside of it. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Specialists are instances of the class "Specialist". They are not themselves classes. The reason for emphasizing that point is that it is a common misconception of people beginning to use the ZPatterns design approach - they conflate or confuse specialists with the class of the things which they intend to use the specialist to gain access to. In other words, they assume that a specialist called "Customers" would always manipulate "Customer" instances, when in fact it might manipulate "SkyDiver" instances. Most of the point of having a specialist is to have a binding point which allows you to decouple your intended use of a thing, from the specific implementation of it. If one misses this point, one will be blind to a wide variety of ZPatterns' useful applications, and at the same time likely to ask why both Racks and Specialists are needed. They are both needed because the Specialist deals with a particular problem-domain aspect of a thing, and the Rack deals with implementation aspects. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

regarding [Zope-PTK] Area based roles?:
Hi all. I've got an idea of something I'm trying to implement, and I'm
wondering if the concept is of use to anyone else.
I've got an Intranet up in PTK. (What a shock, as I'm posting here. :) )
I'm slowly getting people to use it for internal collaboration, et al.
But the main things people are wanting to do are internal to their own
department, with some overlap. So you've got:
+PTKRoot
|
+-Members
| +-John
| +-Sue
|
+-Marketing
+-Technology
Say John is in Technology and Sue is in Marketing. What I want is for
John to have Contributor rights in the context of Technology, and Sue in
Marketing, i.e. John adds a News Item and Publishes it. It shows up in
Technology but not Marketing.
I thought about creating a Technolgy Item ("Release Notes") and a
Marketing one ("Press Release") and then just having a catalog search on
the meta-type of each in the appropriate folder's index_html and give
them all Contributor. But that strikes me as unclean. It would be nice to
have anyone be able to create a Press Release or Release Notes, but only
have them published in their department's context, and merely pending in
others.
Am I making any sense at all? Does anyone see either a need for doing
this or a way to do it? If it requires changes to PTK core, would anyone
be interested in those, or should I throw them in my pile of dirty little
secrets that no one should really know exist?

Re: [Zope-dev] ZPatterns: DropZone example
Thus spake Phillip J. Eby ([EMAIL PROTECTED]): That's all quite true, but it would probably be simplest to do such a thing using AttributeProviders and SheetProviders in the white-box specialists. It does seem reasonable to have those providers talk to an AccountingProcessor object if you want to make your framework talk to different back-ends, but I think it is misleading and incorrect to call AccountingProcessor a specialist, as it's not an application-level service object, but a private implementation helper. Does anybody out there have even the slightest clue about how to go about using AttributeProviders and SheetProviders? A select few terse hints on this subject would really help us (me) figure it out enough to start working on some howto's. Interestingly, you've just given me what may be a motivating example for using Shane Hathaway's DatabaseAPI in conjunction with ZPatterns, assuming of course that I've correctly understood his most recent explanation of the DatabaseAPI product. Am i wrong in thinking that DatabaseAPI is a completely separate solution to the same problem that ZPatters is suppose to address? Personally i have to give DatabaseAPI props for being quite easy to understand and use, while not sacrificing power. sRp -- Scott Parish http://srparish.net/ PGP signature

A select few terse hints on this subject would really help us (me) figure it out enough to start working on some howto's. You might look at some of the recent posts which included an example of using GenericAttributeProviders to read from a MySQL database, and my reply explaining how to use a GenericTrigger to update that same database. Am i wrong in thinking that DatabaseAPI is a completely separate solution to the same problem that ZPatters is suppose to address? Personally i have to give DatabaseAPI props for being quite easy to understand and use, while not sacrificing power. Peter Coad's design approach (which ZPatterns is heavily based on/biased towards) emphasizes four major layers of classes in an application: 1) User Interface (GUI, forms, etc.) 2) Problem Domain (the actual application purpose) 3) Data Management (object persistence/lifecycle management) 4) System Interaction (interfaces w/hardware or other software) ZPatterns is focused on providing tools for transparent mappings between layers 2 and 3, while DatabaseAPI, as far as I can see (and I actually did play around with it today to get a feel for it), is focused on tools for building clean mappings between layers 3 and 4. In my mind, this makes them complementary tools, rather than competitors in any real sense. Indeed, looking at DatabaseAPI has shown me that there are some features I'd planned for ZPatterns (or already started) that I can scrap because DatabaseAPI has them and can easily interoperate. (Personally, I'd like to see a version of DatabaseAPI using PlugIns to structure its user interface, which I think could easily make it even cleaner and easier to use than it already is. It might then also be possible to reuse some of its plug-ins for functionality in areas of ZPatterns. But I digress.) So where do DatabaseAPI and ZPatterns overlap? DatabaseConnector has some functional overlap with Specialist. If you ignore the attribute, sheet, and trigger providing aspects of ZPatterns (and also look only at the raw functionality), the primary difference between a Specialist and a DatabaseConnector is that DatabaseConnectors will probably have methods to delete objects or change their data, which is a no-no for a Specialist because it's an encapsulation breach. Beyond this, there's a significant difference in intent between a Specialist and a DatabaseConnector (IMHO). A Specialist serves as a broker to access objects which fill a certain role in a framework, while a DatabaseConnector represents an object which manipulates "records" which are of "record types" and have "fields". Specialists use Racks to explicitly distinguish between problem-domain and data-domain concerns; you can probably do this with nested DatabaseConnectors but you'll have to do some additional work to support it. ZPatterns could definitely benefit from some ideas found in DatabaseAPI, primarily in the aspect of documenting API's and supporting better design contracts. For example, it would be nice for a Specialist to be able to define the API expected from its Racks, and a for an application framework to somehow define the API expected from the Specialists it will interact with. One could of course use the existing DatabaseAPI product to do these things, but the integration would be less than smooth, since you'd have to make the Specialist ask the Racks for their DatabaseConnectors, or else have a Rack class that delegated to a DatabaseConnector, or something like that. Anyway, I'm going to have to give these possibilities some more thought. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Even if there is a mutex to keep multiple threads from executing queries simultaneously on the same connection, the transactions are going to be whacky. Oracle is obviously transactional.

Does Zope have a mechanism equivalent to the Novell NDS Public access? that is to say: Anonymous = not authenticated. Everyone = authenticated users (that are members of the group) Public = authenticated and anonymous users. In Zope, each user has a set of roles. Any user has the "Anonymous" role. Log-in users may have additional roles. Thus, what you see, should not happen. Users, by default, are not granted the 'Anonymous' role. If you explicity grant the Anonymous role to your users you will get the behaviour you want.

dtml-in eats a list of objects or a list of dictionaries.
Example 1.

Your external methods should return:
l = []
item1 = Item()
item1.date = "21/12/67"
item1.foo = "bar"
l.append(item1)
item2 = Item()
item2.date = "1/1/2000"

In the DTML use the list: dtml-in thelistdtml-var date/dtml-in thelist

Your external methods should return:

Hi David,
I just posted something similar to Zope-Dev:
http://lists.zope.org/pipermail/zope-dev/2000-July/005744.html
Thanks for that. I actually worked out a fairly similar hack myself, which
only did one folder (which was OK for the particular task that I wanted it
to do). Your recursive method has no doubt saved me quite a bit of time in
generalising it. There are still a couple of little question marks in my
mind, though. But before I get to them, I'll just post a sample of what I
came up with (minus most of the gory details of the actual processing I
wanted to do:
def processDTML(self):
"""Process DTML documents within a folder."""
import re
myregex = re.compile(r"(H1.*?/H1)")
thisdoc = self.getFirstChild()
while thisdoc is not None:
if hasattr(thisdoc, 'meta_type'):
if thisdoc.meta_type == 'DTML Document':
# Do processing stuff here
doctext = thisdoc.raw
doctext = myregex.sub(r"\1\n\nH2Profile/H2\n", doctext)
thisdoc.raw = doctext
thisdoc = thisdoc.getNextSibling()
return 'Complete!'
Just for easy reference, this was what you came up with:
import re
def convert_dtml(self):
"""Convert DTML Methods and DTML Documents from old syntax to
new syntax.
Warning: recursive!
This assumes that DTML Method and DTML Document haven't been
subclassed.
"""
print 'convert_dtml: id=%s' % self.title_and_id()
if hasattr(self, 'meta_type') and \
(self.meta_type == 'DTML Method' or \
self.meta_type == 'DTML Document'):
convert(self)
# should this be "isPrincipiaFolderish"?
if hasattr(self, 'isAnObjectManager') and self.isAnObjectManager:
for v in self.objectValues():
v.convert_dtml()
_convert_regex =
re.compile('''!--#(/?)(([^"-]+?|"[^"]*?"|'[^']*?'|-[^-])+?)--''')
def convert(dtml_item):
print 'converting...'
title = dtml_item.title
# like document_src, but doesn't require RESPONSE
data = dtml_item.PrincipiaSearchSource()
print 'data'
print data
newdata = _convert_regex.sub('\g1dtml-\g2', data)
print 'newdata'
print newdata
print 'end'
dtml_item.manage_edit(newdata, title)
Some questions I have in my mind:
1. I used "raw" and you used "PrincipiaSearchSource()" . The reason I used
raw was because I wanted to be sure that what I got wasn't munged in any
way, and that what I put back reflects what was actually there before.
2. You used the "manage_edit()" method, whereas I just assigned to the
"raw" property. My way seems to work OK, but I'm not sure how yours works:
I assume it brings up an edit page in the browser for each document?
3. I don't like resorting to testing the "meta_type" for a particular
string value. As you noted in your code, it doesn't allow for subclassing,
so it's not fully general.
4. I was surprised that the import statement (not to mention
"re.compile()") could be put outside of the method definition, considering
that Zope's external methods grab on to individual methods within a Python
module.

[Zope] What is the best way to do this?
Hello zope-masters, I humbly ask your advice on several matters. I am making an internal website for a statewide student activist group with many members. It will hopefully feature discussion boards, a contact database, and a calendar of events. I want to make the users of the site part of the contact database, so that an entry in the database (a name, phone number, etc.) can be easily "promoted" into a user with a password and varying priveliges based on his/her role (volunteer, core member, board chair, etc.) Another feature I want to include is regional specialization - each contact/user, calendar event, and forum has an associated "region" - statewide or a specific campus or something in between. That way a user's default view of the statewide calendar won't be cluttered by irrelevant events, and a search through the contact database would by default only return results pertaining to the user's region. I've tried building some custom zClasses but when things start to get complex the dtml code gets really messy, so I think I should use external methods to do most of the work. Basically I'd appreciate any advice on how to put these ideas into code or pointers to relevant documentation. I don't mean to sound like "here's my very complicated plan, write the code for me", I just need some tips on how to get started.

RE: [Zope] What is the best way to do this?
alex, IMHO when you try to do stuff using ZClasses and DTML and it starts looking too complex to you then it is. DTML is made for presentation, not for driving an application. a very sound architectural approach, and one that scales very well as your site and organzation grows, is a base of python-based zope products with ZClasses that derive from them. all the logic happens in the python product and all presentation is in the derived ZClasses. this will not only speed up your code but it will also make it easy to control presentation because that is stored in the ZODB and can be manipulated through the web. the only drawback is that a change in the underlying python product code requires you to restart zope. if you're like me and can't stand messy and kludgy code you will appreciate the extra effort spent on writing a real python zope product. for starters look at "How to create a Boring Product" at http://www.zope.org/Members/gtk/Boring/HowTo-Boring . this will explain some of the structure that is needed for a python class to become a "zope product". another guide is at http://www.zope.org/Members/Zen/howto/ProductAPITutorial . for the latest changes that need to be considered when writing a product for zope 2.2 read brian's guide at http://www.zope.org/Documentation/How-To/ProductAuthorUpdateGuide . a good deal of knowledge can be gained from simply looking at the code of products available in your zope install under zope/lib/python/Products. jens Jens Vagelpohl [EMAIL PROTECTED] Software Engineer www.digicool.com Digital Creations (888) 344-4332 Got Zope? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Alex Gould Sent: Tuesday, July 04, 2000 21:11 To: [EMAIL PROTECTED] Subject: [Zope] What is the best way to do this?

[Zope] WorldPilot and UW-IMAP?
Greets, I'm experiencing an issue with WorldPilot not showing the body of messages that have attachments. I can only guess that this is because WorldPilot was designed for use with the Cyrus IMAP server and I'm using it on a stock RedHat system, which I presume sports UW-IMAP. I've searched around and not found too much detail about UW vs. Cyrus for WorldPilot. Can anyone enlighten me as to whether or not my problems are due to using UW-IMAP and generally whether it's worthwhile to suffer a Cyrus install, vs. a hack or patch to WorldPilot? I frankly don't want or need what Cyrus has to offer. I really like WorldPilot and I'm trying to push it on an office full of people, but you can imagine how thrilled they are about not being able to read select messages. They are starting to make noises about wanting to go back to Outlook now.

[Zope] Comparing two dates WITH time?
Hello All, I need help again. How do I compare two dates that include full timestamps? If I try date_updated = ZopeTime() it works only for dates that do not include times... as soon as you have a time in the date_updated field, If the date_updated contains only a date (200/07/04 for example) it works flawlessly. What am I doing wrong? (Note that if I set the date_updated to yesterday with a time, it works also. is this a bug, or what? My logic would tell me that 2000/07/04 12:00:00 GMT+1 is smaller than 2000/07/04 11:59:00 GMT+1). Please someone tell me what's going on, I am beinning to feel that I am either asking too stupid questions, or I have problems no-one has any clue about. I am not sure what'd frighten me more... ;-) Best wishes, Nils ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
